I run a BLtouch.
I would like to automatically re-calibrate the Z-offset of the BL Touch.
Can i first Z home the bed first by using the motor stall function on Z axis,
then re-home Z axis using the BL touch.
The resulting difference should be the exact Z offset for the BL touch.
This should all be able to be done in a Macro i believe.
This would involve setting z endstop to motor stall, the on second pass setting endstop to bltouch.
